If offered at all, use only a few plain air-popped pieces with no butter, salt, or flavor coatings. Unpopped kernels can chip teeth or cause choking. Avoid movie-style, kettle, and microwave-bag varieties.
Popcorn is made by heating dry corn kernels until they puff, sold as air-popped, microwave, kettle, and movie-style snack varieties. Plain popcorn is mostly starch with some fiber.
Common toppings include butter, salt, caramel, cheese powders, and spicy coatings. Microwave bags include oil and flavor residues that are richer than plain popped corn.
Seasoning sachets leave oily powder on counters and bowls. Movie-style and kettle corn residue on bowls and shared snack bags is a common accidental exposure point.
